Whether you already have a Known Traveler Number (KTN) or are applying for TSA PreCheck for the first time, understanding how LATAM Airlines handles TSA PreCheck can save time and reduce confusion before your flight.
Transportation Security Administration TSA PreCheck is a trusted traveler program operated by the U.S. government. It allows approved travelers to use expedited security screening lanes at participating airports across the United States.
Passengers using TSA PreCheck generally enjoy benefits such as:
Shorter airport security lines
Keeping shoes on during screening
Leaving laptops inside bags
Keeping light jackets and belts on
Faster overall airport processing
The program is especially useful for frequent travelers flying between the United States and international destinations served by LATAM Airlines.
Yes, LATAM Airlines participates in the TSA PreCheck program for eligible flights departing from participating U.S. airports. Travelers with an active Known Traveler Number can add their KTN during booking or after purchasing their ticket.
However, TSA PreCheck availability depends on several factors:

Eligible travelerMust have approved TSA PreCheck membership
Participating airportDeparture airport must support TSA PreCheck

If any information does not match exactly, the TSA PreCheck indicator may not appear on your boarding pass.
A Known Traveler Number is the identification number assigned to travelers enrolled in:
TSA PreCheck
Global Entry
NEXUS
SENTRI
The KTN is usually 9 digits and must be added to your airline reservation to receive TSA PreCheck benefits.
The easiest way to add TSA PreCheck to LATAM Airlines is during the initial booking process.
Go to the official LATAM Airlines booking portal and begin your reservation.
During the traveler details section, enter:
Full legal name
Date of birth
Gender
Passport information (if required)
Ensure your information exactly matches your TSA PreCheck enrollment records.
Look for a field labeled:
Known Traveler Number

Trusted Traveler Number
Enter your KTN carefully without spaces or errors.
Finalize payment and complete your reservation. Once processed, your TSA PreCheck status should attach automatically if your information matches TSA records.
If you forgot to add your Known Traveler Number during booking, you can still update your reservation later.
